GUN WITH ADJUSTABLE CRANKED AXLETREE.

Application filed February 10, 1914.

To @ZZ flo/tom 'it may concern.'

Be it known that I, KURT KLnrrn, engr neer, a subject of the German Emperor, residing at et?) Marsehallstrasse7 Dusseldorf, Germany, have invented certain new and useful Improvements in Guns with ridjustable @ranked Axletrees; and I do herebj7 declare the following to be a full, clear, and exact description of the invention7 such as will enable others skilled in the art to which it appertains to make and use the same.

rlhe present invention relates to guns h aving adjustable cranked axle-trees. for setting the gun to an elevated or depressed tiring position.

According to the present invention the masses are so distributed with respect to the wheel axis that in the traveling position of the gun, that is when it is limbered up, these masses counterbalance each other about the wheel axis so that the pressure exerted by the trail on the limber is entirely or nearly removed.

In the accompanying drawings., Figure l shows the gun in depressed position, and Fig. 2 in elevated position. Fig. 3 is an enlarged sectional view through the hub et one of the wheels. Fig. is a. fragmentary view of the locking bolt.

In the normal traveling position, shown in Fig. l. the trunnions oi the gun are in line with the hollow axles (t of an axle-tree crank 7, the axles a', being releasably held in this position by locking means which comprises a plug c fitting in the outer end ot the axle and having a handle Z for moving the plug with its bolt g against the pressure of a spring L which latter encircles a reduced portion of the bolt and has one end bearing against an abutment z' in the axle a. The plug is slotted as at e to permit its longitudinal movement without necessitating removal of the linch pin f by which the wheel is held to the axle. `When the gun is to be moved Speoication of Letters Patent.

serial No. 817,843.

from the depressed position, shown in Fig. l, into the elevated tiring position, shown in Figt 2, the bolt g is withdrawn from its locking position in line with the trunnion of the gun permitting' the axle-tree, together with the gun carriage, to be moved in the direction of the arrow, Fig. l, and into the position shown in Fig. 2, the bolt 'r/ then taking into a hole In in the trail. This movement has the effect ot' raising the gun from lower to higher. position. It can again be lowered for the purpose ot traveling to so distribute the masses of the gun barrel and other parts that they balance about the wheel axis. The trail therefore exerts no y or at least a very inconsiderable, pressure on the shaft of the limber.

I claim as my invention l. In combination7 a gun, a carriage to which said gun is pivoted, a cranked axle mounted on the carriage, and means for securing said crank in line with the pivots ot said gun to counterbalance the masses about the wheel axle in traveling.

2. In combination with a gun and its Carriage to which the gun is pivoted, a cranked axle mounted on the gun carriage and means for securing the crank of the axle in line with the gun pivots or at a lower point on the gun carriage when the gun is elevated.

3. In combination with a gun and its carriage to which the gun is pivoted, a cranked axle mounted on the gun carriage, and means for securing the crank of the axle in line with the gun pivots or at a lower point on the gun carriage to the rear of the pivots when the gun is elevated.

In testimony whereof, I have signed this vspeeiiication in the presence of two subscribing. witnesses.
